Application led March 25, 1921. Serial No. 455,507.

This invention relates to machines for operating on soles and. more particularly for providing the margin of a sole, such as an insole, with an edge adapted to permit attachment thereto of the upper.

- In a certain type of shoe, the insole is provided with a wing and with an o'verhanging shoulder inside and above the Wing to permit attachment thereto of the upper.

One of the objects of this invention, therefore, is to provide a machine for operating on soles, having provisions for slitting the sole edge therealong and for cutting the sole face along but inside of the solemargin so as to provide a wing with a shoulder above and inside of the wing.

Another object is to provide a machine of the character described in which the operation of the cutting means is effective and efficient. y

Further objects will appear from the detail description taken in connection with th accompanying drawing, in which:

Figure 1 is a side elevation of a machine illustrating an embodiment of this invention;

Figure 2 is an enlarged section on 2 2, Figure 1; p

Figure 3 isa perspective of the tool;

Figure 4 is an elevation; and

Figure 5 is a section through an insole as formed in the machine.

Referring to the yaccompanying drawing,I and more particularly to Figure 5, the insole 1, as'shown, has a wing 2 thereon with an the Aline overhanging shoulder 3 arranged above butv inside o the wing. This sole Lus formed by slittingthe sole edge therealong on the -line 4, thereby forming a lip 5 and by severing the lip by a cut taken along but inside of the sole margin and at an acute angle so as to form an overhanging shoulder 3.

The sole is formed by a tool 6 asshown in Figure 3, which, in the particular embodiment of this invention, is a stationary tool which can be placed on any suitable channeling machine as shown in Figure 1, The tool has a slitting edge 7 forming a slitting knifewhich inclines u wardly towards the backtso as to provide or strength` and further hasv a cut-ting edge 8 forming av sole face cutter which alsothickens towards the back and which is formed on a shank-9 provided with a slot 10`so that the sole face cutter can be clamped to the slitting cutter by a screw 11 threaded into thebody of the tool 6.' The sole face'cutter 8 intersects but is arranged at an acute angle to theyslitting knife 7 and the cutting edge of the slitting knife is arranged in advance of the cutting edge of the sole face cutter. Either or both of the slitting knife andv the sole face cutter can, of course, be sharpened by discon-l necting Athem and wear can be taken up by adjustment provided by the clamping screw l1 The tool can be placed in any suitable machine, such as the Well known form of channeling machine shown in Figures 1 and 2, and which comprises a base 12 havin hinged thereto at 13 a frame14 normally l(held towards the base 12 by a spring 15 encirclin -a bar 16 suspended from the frame 14 an passing through the base 12 and provided with a tension screw 17. The base is provided with a shaft 18 and a counter-shaft 19, while the frame is provided with a shaft 20, the shafts being interconne ted by gears and the shaft 19 has a knurled wheel 21 while the shaft 2O has a roll 22. A gauge 23 controlled and positioned by an arm 24 is also provided. A guide 25 is further provided to guide the sole in and between the rolls 21 and 22. t

The construction so far described is common in the art and further detail description thereof is :unnecessary since it is thev structure of, the ordinary channeling machine, such as illustrated in the Stanbon Patent No. 607,140,Ju1y 12, 1898.

The frame 14 has mounted thereon the tool 6. This may be accomplished by screws 26 taking through slots 27 in the tool; the tool is thus mounted beyond the gauge 23 so as to receive the sole fed between the rolls 21 and 22.

In operation, the sole is fed between the rolls 2l and 22, the edge thereof being positioned by the gauge 23 which may be operated during the operation of the machineso as to providefor extension edges in the usual manner. These rolls will, therefore, move the sole against the tool as shown in Figure 4, therebyv causing the knife 7 to slit the sole edge therealong and thereafter cause the sole inside of the sole margin. In view of the' fact thatthe slitting knife operates in advance of the sole face cutter, the slitting is actually accomplished in advance of the severing of the lip; with this construction the ysole will be smooth and not only will breakage of the cutting edges be prevented, but the cut is a smooth andeven one as the .slitting is completed before the severing of the lip formed by the slitting operation and the formation of the overhanging shoulderis started.

. It is obvious that various changes may be made in details of construction without departing from the spirit of this invention; it is, therefore, to be understood that this in'- vention is not to be limited to the specific letails shown and described.

Having thus described the invention what is claimed is: v

1. A machine for operating on soles, coinprising, a support adapted to 'sustain' the sole and present the edge thereof, a blade adapted to slit the sole edge therealong and inwardly from its margin, and a blade arranged to intersect said slitand adapted to cut the sole face along but inside of the sole margin so as to join the slit, said slitting gage. operating in advanceof said cutting 2. A machine for operating on soles, comprising, a support adapted to sustain the sole and present the edge thereof, a blade adapt; ed to slit the sole edge therealong, and inwardly from its. margin, and a blade arranged to intersect said slit and adapted to cut the sole face at an acute angle and along but inside of the sole margin so as to join the slit, said slitting blade operating in advance of said cutting blade.

3. A machine for operating on soles, comprising, a support adapted tosustain the sole and present the edge thereof, a blade adapted to slit the sole edge therealong, and inwardly from its margin, and a blade arranged to intersect said slit and adapted thereafter to cut the sole face at an acute angle and along but inside of the sole margin so as'to join the slit.

4. A machine for operating on soles, comprising, a support adapted to sustain the sole and present the edge thereof, a blade adapted to slit thesole edge therealong and inwardlyv from its margin, and a blade arranged to intersect said slit and adapted to cut the sole faceV along but inside of the sole margin so as being directed inwardly so as to form an undercut shoulder on the sole. co

5. A machine for operating on soles, comprising, a support adapted to sustain the sole and present the edge thereof, a blade adapted to slit the sole edge thercalong and inwardly from its margin, and a blade arranged to intersect said slit and adapted to cut the sole face along but inside of the sole margin so as to join the slit, the tip of said cutting blade being directed inwardly so as to form an undercut shoulder on the sole, and said tiphaving its cutting edge rearwardly of the cutting edge of said slitting blade.
